Rerouting Colonial Botany in Jamaica Kincaid's Among Flowers: a Walk in the Himalaya 'Gardenworthy': Rerouting colonial botany in Jamaica Kincaid's Among Flowers: A Walk In the Himalaya fill Didur Plants are as diverse as people. Some are polite, attractive guests you invite into your domain; others are nosypests who creep in uninvited and take root. (Chicago Botanical Garden website) Vermont, all by itselfshould be Eden andgardenworthy enough. But apparently, I do notfind it so. I seem to believe that I will find my idyll more a true ideal, only ifI canpopulate it with plantsfrom another side ofthe world. any plants considered prized additions to gardens over the last two centuries are embedded M in a set of material and textual practices linked to the history of colonialism and plant­ hunting in South Asia. What connects this history to contemporary gardening culture is a shared interest in domesticating foreign plants while still retaining an aspect of their exotic origins. This essay will investigate different textual practices used by plant hunters in South Asia to represent their encounters with the strange and unfamiliar, and consider how this has influenced the imag­ ined and actual domestication of exotic plants in European and NorthAmerican gardens. The OED defines an exotic, with reference to plants, as "introduced from abroad, not indigenous" but also "having the attraction of the strange or foreign, glamorous." My reading of Jamaica Kincaid's AmongFlowers: A Walk in the Himalaya (~oo5) [hereafterAmongFlowers] attempts to account for the tension between conceptions of the foreign and the domestic that informthe desirability ofcollect­ ingso-called exotic plants, and to considerwhat metaphorical implications this tension might have for reading Kincaid's own diasporic subject position in her travel narrative about plant-hunting in Nepal. I compare and contrast Kincaid's arguably counter-colonial narrative with early plant­ hunting memoirs set in and around the Himalayan region, including Joseph Dalton Hooker's The Himalayan Journals (1854), Frank Kingdon Ward's The Riddle of the Tzangpo Gorges (19~4) and, more recently, Roy Lancaster's Plant Hunting in Nepal (1981). Specifically, I consider how these different plant hunters narrate their encounter with the Himalayan landscape and examine how they frame their perception of botanical specimens like the 'high alpine' Rheum nobile (noble rhubarb). This essay is part ofa larger project that reflects onthe role plant-hunting memoirs have played in the globalization of alpine plants and practices associated with rock gardening culture from the nineteenth century onward.' While plant-hunting literature and activities appear to be largely a colonial project geared toward advancing a scientific agenda and economic botany, as well as domesticating certain types ofplants for European gardens, I demonstrate that narratives about these journeys are also fraught with anxieties concerning colonial authority. Reading these earlier plant-hunting texts in relation to Kincaid's account of her Nepal trip can provide the urban gardener with a worldly frame for understanding contemporary horticultural practices, pointing to their implication in colonial history, and disrupting popular attitudes toward gardening as a leisure activity pursued outside the bounds of cultural politics. Jamaica Kincaid's Among Flowers describes a three-week seed hunting expedition in Nepal during the fall of ~OO~. Simultaneously invoking and subverting the genre of colonial travel writing and plant-hunting practices, this book chronicles the experiences of Kincaid and her companions as they set out to gather the seeds of as many"gardenworthy" (Kincaid ~ooS, uS) plants as they can find during their trip. The term gardenworthy is used by Kincaid to refer to the kind of plants that can be easily cultivated in the cooler temperatures associated with gardens in Europe and North America. As Kincaid's narrative makes visible, however, the definition of what counts as garden­ worthy is quite slippery, and involves a complex cultural negotiation not necessarily dependent on climatic conditions. The use of the term is quite common in popular gardening books, magazines, and websites. Gardenworthy is used to describe the hardiness as well as the appropriateness of growing certain plants in particular climatic zones. When Kincaid first mentions this concept inAmongFlowers, she describes how the botanists she travels with debate the best route for the trip, and she emphasizes that" [e]very square foot of terrain must be carefully pored over so that not a single garden-worthy plant is missed, the poor collector not knowing ifhe will ever be able to come this way again" (3~). Here, "garden-worthy" appears with a hyphen that is subsequently dropped, something Kincaid suggests has to do with her growing sense of connection to the plantsmen's vocabulary. "Gardenworthy" Kincaid explains, has a sweeping authority, a confidence in judgement that they, the plantsmen have. It's most likely that I, in trying to copy them, trying to enter the club so to speak, used it in that way. But my own way of saying it, still trying to borrow their confidence and authority would have used the word with a hyphen. The [initial use of the] hyphen would have been me trying to prop up my slender association with the whole enterprise (~oo7, email to the author). The initial instability of Kincaid's use of"garden(-)worthy" in the story of her plant-huntingtrip in Nepal can be read as an expression of her liminal status in relation to the activity. Indeed, she has used this word previously with a hyphen in her account of a seed hunting trip in China anthologized in her collection, My Garden (Book): [hereafter My Garden]. A much less physically challenging undertakingthanthe Nepal trip, Kincaid explains thatshe and hertravellingcompanions were bussed between plant-hunting locations over terrain that held very little interest for the group. She com­ mentshow, 174 nlDUR ______J For a very long time (or so it seemed to the botanists and to me, too-I was beginning to see things only from their point ofview L.. Dwe saw nothing of interest L.. ] scrub and scrub and scrub (scrub as an entity holding nothing that the botanists thought of as garden-worthy, and that whole idea, .garden-worthy' will eventually have its own enemies, its own friends and passionate supporters) (1999, 198). Learning to see things from the perspective of the botanists and familiarizing herself with the "friends" and"enemies" of what counts as garden(-)worthy are things that Kincaid takes up with deeper interest inAmong Flowers. In Nepal she describes herself as being initiated into "the club" offamous plant hunters and horticulturists (such as Lancaster, Hooker and Ward) who have written about botanical explorations in the same region she visits and with whose accounts she is well­ versed. I would like to suggest, however, that Kincaid's entry into this world involves inhabiting the role of the explorer in a manner that seeks to appropriate and change, and not simply debunk, the terms for how the activity of plant-hunting is understood. Of course, Kincaid's interest in gardening culture's colonial underpinnings has been a defin­ ing quality of her creative writing throughout her career. Her first novel, Annie]ohn, for example, uses references to indigenous and foreign plants and trees (guava, Psidium guajava, and bread­ fruit, Artocarpus altilis, respectively) as a way of indirectly highlighting the impact of slavery and colonial practices onAntigua's cultural and economic history. Born in colonial Antigua in 1949, a descendant of slaves, Kincaid moved to the US in 1966, where she began her career as a staffwriter for The New Yorker. My Garden anthologizes Kincaid's personal essays about the history ofcolonialism and botanical exploration, her own growing interest in gardening culture, and places her attrac­ tion to these topics at the forefront of her current work as a writer. As some critics have noted, however, it is often an unsettling experience to read Kincaid's reflections on her activities and interests as a gardener. As Jeanne C. Ewert observes, "On first reading L.. ] My Garden (Book): seems to present a fairly straight forward, and often engaged indictment of the colonial practices of appropriating, renaming, and relocating plants from their native countries to other parts of the world." Ewert and others have noted, however, "a closer look at Kincaid's garden L.. ] reveals the degree to which Kincaid herself engages in the very practices she criticizes" ('2,006, 113). While I agree that it is possible to identify parallels between Kincaid's and the colonial plant hunters' passion for gardening and exotic plant acquisitions, it is also impossible to ignore the "layered self­ consciousness" (Nixon '2,010, lO) of Kincaid's narrative, something that Rob Nixon regards as a defining quality of travel writing by Black postcolonial writers. Like the post-apartheid game park experience in South Africa that Nixon reflects on in his essay, "Stranger in the Eco-village," the contemporary Himalayan plant-hunting expedition could be described as "a spaced marked as non-coeval with the world around it and whose implication in modernity is suppressed" (8). Kincaid's entry into this "anachronistic space," (8) and her decision to narrate its pleasures and challenges while also foregrounding how her racial difference, "disrupts the smooth optics of tourism" (9) that characterize trekking and mountaineering culture in Nepal, setting her apart from the other plant hunters as someone who not only looks but is also looked at. One among many examples of this type of disruption inAmong Flowers includes Kincaid's story of a Nepalese woman who was fascinated by her "braided-into-cornrow hair" (Kincaid '2,005, 46). "She asked," recalls Kincaid, "if I could make her own hair look like mine. I did not know how to tell her that my hairdo L.. ] was made possible by weaving into my own hair the real hair of a woman from a part of the world that was quite like her own" (46).

Milne3,4, Mingyu Wang2*, Bingbing Liu1* 1 State Key Laboratory of Grassland Agro-ecosystem, School of Life Science, Lanzhou University, Lanzhou, Gansu, China, 2 MOE Key Laboratory of Cell Activities and Stress Adaptations, School of Life Sciences, Lanzhou University, Lanzhou, Gansu, China, 3 Institute of Molecular Plant Sciences, School of Biological Sciences, University of Edinburgh, Edinburgh, United Kingdom, 4 Royal Botanic Garden Edinburgh, Edinburgh, Scotland, United Kingdom Abstract Background: Rheum nobile is an alpine plant with translucent bracts concealing the inflorescence which produce a ‘‘glasshouse’’ effect promoting the development of fertile pollen grains in such conditions. The current understanding of the adaptation of such bracts to alpine environments mainly focuses on the phenotypic and physiological changes while the genetic basis is very limited. By sequencing the upper bract and the lower rosulate leaf from the same R. nobile stem, we identified candidate genes that may be involved in alpine adaption of the translucent bract in ‘‘glasshouse’’ plants and illustrated the changes in gene expression underlying the adaptive and complex evolution of the bracts phenotype. Results: A total of 174.2 million paired-end reads from each transcriptome were assembled into 25,249 unigenes. By comparing the gene expression profiles, we identified 1,063 and 786 genes up-regulated respectively in the upper bract and the lower leaf. Functional enrichment analyses of these genes recovered a number of differential important pathways, including flavonoid biosynthesis, mismatch repair and photosynthesis related pathways.

  • Hooker Is Calling English.Rtf
    „Hooker is calling…..“ In 1854 Joseph Dalton Hooker, a well known british botanist, travelled to the kingdom of Sikkim in the himalayan mountains…. Nearly 158 years later we are on our way to the smallest state of India, nestling between Tibet, Nepal and Bhutan. We, that is a group of 12 perennial-plant-lovers of the ISU from 5 nations. Our swedish colleague Jonas Bengtson has been in Sikkim a few times and we can accompany him this year. We nearly all know each other, have been on excursions together,which gives us a good and secure feeling. I have never been to India before, but my head is full of clichées like blocked roads, cramful busses, colourfully clad people, prayer flags, dirt and garbage – but I am nevertheless surprised to see exactly that! Our group has been divided, we go from the airport of Bagdogra to Gangtok, the capital of Sikkim, in three crosscountry cars. It is nearly impossible to take in everything we see: A barfooted, emaciated man with a washing machine on his back, three very fat ladies in pastel saris hung with tassels and the prim schoolkids in uniform with snowwhite stockings, bows in their neat plaits, colourful kiosks with garlands of bonbons, dirty legs of a sleeping man stucking out from under a corrugated iron shelter, mud, lovingly painted lorries… My shock is diminishing only slowly – there are no rules concerning the traffic, the quickest and boldest one with the loudest horn wins. Our drivers look like children, stinking exhaust gases get into the car.

  • Phylogeny of Rheum (Polygonaceae) Based on Cpdna Trns-G Sequences
    Pak. J. Bot., 52(4): 1345-1351, 2020. DOI: http://dx.doi.org/10.30848/PJB2020-4(43) PHYLOGENY OF RHEUM (POLYGONACEAE) BASED ON CPDNA TRNS-G SEQUENCES WEIWEI LI AND AILAN WANG* School of Life and Sciences, Ludong University, Yantai, 264025, Shandong, P. R. China *Corresponding author's email: [email protected] Abstract Rheum L. is a perennial herb of Polygonaceae, with about 60 species, most of which are distributed in the Qinghai- Tibet Plateau (QTP). Due to the unique habitats of the QTP, Rheum L. was one of the typical representatives for studying the species diversity of this region. To investigate the monophyletic origin of this genus and evaluate its infrageneric relationships, a total of 27 individuals distributed in seven of eight sections of Rheum (only excluding Sect. Orbicularia) were collected in the QTP and adjacent areas. Molecular phylogenetic trees were reconstructed based on cpDNA trnS-G sequences. The results showed that the monophyletic origin of Sect. Palmata was supported, while another six sections (Sect. Rheum, Sect. Acuminata, Sect. Deserticola, Sect. Spiciformia, Sect. Globulosa and Sect. Nobilia) were found to be paraphyletic origin. Rh. kialense of Sect. Acuminata clustered as a subclade with Rh. Likiangense 3 of Sect. Rheum, Rh. pumilum and Rh. sublanceolatum of Sect. Deserticola. Rh. alexandrae and Rh.nobile, the only two species in Sect. Nobilia, also scattered in different groups. The monophyletic origin of the monotypic Sect. (Globulosum) was also unsupported, and it was found to be clustered together with Rh. nanum of Sect. Deserticola in the ML tree. In conclusion, the phylogeny of Rheum based on cpDNA trnS-G sequences may serve as a reference for exploring specific patterns of rapid speciation in QTP and similar geographical environment.

Two large translucent bracts of the species put on the inflorescence such as a parasol and selectively absorbed UV radiation, though visible light almost completely transmitted. It was shown by high performance liquid chromatography (HPLC) that much amounts of UV-absorbing substances are accumulated. Seven flavonol glycosides were isolated by various chromatographic techniques such as paper, column and HPLC, and identified as quercetin 3-O- sambubioside, quercetin 3-O-galactoside, quercetin 3-O-glucoside, quercetin 3-O-arabinoside, kaempferol 3-O-galactoside, quercetin 3-O-(2Љ-acetylgalactoside) and quercetin 3-O-(acetylgluco- side) by UV spectral survey, LC-MS, 1H and 13C NMR, acid hydrolysis, and direct TLC and HPLC comparisons with authentic samples. Thus, it was proved that the flavonol glycosides, especially quercetin 3-O-galactoside and 3-O-glucoside, act as the important UV shields in the translucent bracts of D. involucrata and protect the inflorescence from noxious UV radiation.
